HOSE COUPLING.

Application filed. August 12, 1921. Serial No. 491,728.

To all whom it may concern. 7

Be it known that I, ALPHoNsn MoYrJN, a subject of the King of Great Britain, and resident of the city of Edmonton, in the Province of Alberta, and Domini-on of (anada, have invented certain new and useful.

Improvements in Hose Couplings, of which the following is a specification.

This inventlon relates to improvements in hose couplings, and particularly to the.

washer or gaskets therefor, and the objects of the invention are to prevent loss or dis placement of the washers when the hose is uncoupled and the parts of the coupling separated. In the ordinary hose coupling the washer is retained in the same by friction or placed in a groove therein and is readily displaced or lost, and, when lost, considerable water According to the present invention, the

, washer or gasket is formed with an extension extending in a slot formed in a projection on one member of the hose coupling, the

washer being retained by a locking key which extends through the projection, all as hereinafter more fully set forth and described in the accompanying specification and draw ings.

In the drawings: I I Figure 1 is a perspective view of the hose coupling.

Figure 2 is alongitudinal sectional view. Figure 3 is asectional view of the female coupling. Y

Figure 4 is a perspective View of the washer or gasket.

Figure 5 is asectional perspectiveview of an alternative form of the invention. Y .In the drawings, like characters of ref- ,erence indicate corresponding partsin all the figures. I

Referring to the drawings: A indicates the male member and B, the

female member of the coupling, the male tubular con.

member being connected to a necting neck 10 while the female member. is formed with a central opening which extends around andengages the fiangell on t e connecting neck 12. It may be stated thatv the invention may be applied of they usual form of hose coupling.

In accordance with the present invention. the connecting washer C, usually located in the base of the channel member, is formed with an extension 13 which extends in a slot 14L formed in a projection 15 onthe female to a variety member B, the washer being-retained in position by means of a locking key l6.'shown* in the form f a split "key whichextends through a suitable perforation 17 in the r'ojection and a perforation 18 in the-washer;

The male member has theusual screwthreaded connection with the female member. f

It will be seen by the present invention the washer is firmly locked in position, and i it will be impossible-for it to become un loosened or displaced. The washermaybe. made of rubber, leather, or any-'suitableand tough material. v i

vAs many changes could be made 111 11118 above construction and many apparently widely different embodiments of my invention within the scopeof the claims, constructed WltllOLlt' departing from the splrlt or v scope thereof, it is intended that all matter contained in the accompanyingspecificationand drawings shall be: interpreted as illustrative and not in a limiting sense.

In the alternative form of the invention shown in Figure 5,"slots 2U are formed in opposite sides of the female member through which projecting lugs 21 on the washer ex-1 I tend, I I What I claim as my invention is: y 1. In a coupler, a coupling member havlng a'recess, a washer having an extension extending in the recess, a locking key extendingthrough the coupling member and engage;
